Application filed April "1'7, 19221 Serial No. 5513351.

To all whom it may c'onccw't:

Be it known that VVA'LTER' then and iIERBERT L, Trrorms-citizensof the United States, residing at Palco, in the county of Books and State of Kansas, have invented certain new and useful Improvements in ashing Machines, of which thefollowing" is a specification. I

This invention relates to washing machines, particularly to thatfclass of washing machines which are manually operated, and our primary object is to provide a washing machine in which clothes can be thoroughly cleaned, without the necessity of rubbing the clothes, which not only wears the clothes out, but also has a tendency to strip the buttons from same, also avoid the pounding of the clothes to clean same, which pounding has a wearing effect upon the clothes being cleaned.

Our invention comprises a rectangular body or tub in which the clothes to be cleaned are placed, and a pair of reciprocating plungers mounted in each end of the tub and having the reciprocating plungers con nected to a rocker arm through suitable pitmans, and having an operating handle mounted on one end of the shaft to which the rocker arm is secured, for reciprocating the pitmans towards and away from the clothes which are placed in the center of the tub. V

A still further object of our invention is to provide a washing machine of this character, that is simple in operation and construction, durable, eiiicient for the purpose intended, and one that can be manufactured and placed on the market at a relatively low cost.

These and like objects will be better understood as the description proceeds, and as same is specifically pointed out in the appended claims.

Referring to the drawings, which form a part of this specification,

Figure 1 is a top plan view of our washing machine showing the operating mechanism for same.

Figure 2 is a longitudinal section taken on lines 2-2 of Fig. 1.

Figure 3 is a horizontal vertical section taken on lines 33 of Fig. 2, and

Figure 4 is a vertical section through one of the reciprocating plungers.

Referringto-the drawings in detail, like characters 'will be, used to designate like parts in the different views.

The numeral 1 denotes the body or tub of the washing machine, which is preferably rectangularinshape, which is provided with a door in'the top of the tub. Positioned on top-of the tub are'supports 3 and 4 respectively, which act as a'bearingfor the operatingishaftf). 7

Positioned within the tub. 2 and at op poslte ends of same are the reciprocating plungers 6 and 7 respectively. Each of the reciprocating plungers are approximately U- shaped in cross section, thus comprising a pair of walls 8 and 9 having their ends closed as at 10. Each of the walls 8 and 9 are provided with a series of alined openings 11 therein, the purpose of which will be better understood as the description of our invention proceeds. In order to strengthen the reciprocating plungers 6 and 7, a rein forcing strip is placed between the walls 8 and 9, which is secured to the clamp 13 by means of bolts or other fastening means 14, the said bolts 14 passing through both walls 8 and 9 to reinforcing strip or block 12 and the clamp 13. Secured to the top of the tub adjacent each end of same are guide plates 14 and 15 respectively. The guide plates 14 and 15 are provided with a longitudinal opening 16, which permits passage or movement of the clamps 13 through same. A block 17 is positioned in each of the guide ways 14 and 15, and is slidable therein. The clamp 13 of each of the reciprocating plun gers, passes up and through the openings 16 in the guideways and over the block 17, and each of the clamps 13 are connected as at 18 to the pitmans 19, which in turn are connected at opposite ends to the rocker arm 20 mounted on the operating shaft 5.

In the operation of our invention, the clothes are placed within the tub through the door 2, and the handle 21 keyed to one end of the shaft 5 is moved back and fourth which causes the rocker arm 20 to move the plungers 6 and 7 towards the center of the tub, which movement compresses the clothes and on reverse movement of the plungers 6 and 7, a partial vacuum is created which materially assists in cleaning the clothes within the tub 2. The alined openings 11 in each of the plungers 6 and 7, permit the passage of water therethrough, thus causing the water to be continually in circulation, causing same to pass back and forth through the clothes within the tub. Y

While we have shown and described the preferred form of our invention, we realize that various minor changes may be resorted to, without departing from the spirit and scope of the invention as claimed, therefore, we do not wish to limit ourselves to the exact details of construction shown, nor to the combination and arrangement of parts.

What we claim as new and desire to secure by Letters Patent is 1. In a washing machine, comprising a tub rectangular in shape, reciprocating plungers positioned in opposite ends of the tub, a rocker arm positioned on top of the tub, means for connecting the opposite ends of the rocker arm to the reciprocating plungers and guide means for the reciprocating plungers positioned on top of the tub at opposite ends of same.

2. In a washing machine, comprising a substantially rectangular frame, reciprocating plungers positioned in opposite ends of said frame, each of said plungers comprising a pair of spaced plates having their bottom portions closed, said plates being provided with registering apertures arranged at spaced intervals, a rocker arm positioned on top of said frame intermediate the. ends thereof, means for connecting the opposite ends of the rocker arm to said plungers, and guide means on said frame cooperating with said reciprocating plungers to permit the slidable movement of the latter in said frame.

In testimony whereof we affix our signatures.
